The diagram below shows all the antinodal lines (dashed) and nodal lines (solid) due to two-point sources tapping a water surface (the two dots in the middle of the circle are the two-point sources). The sources are separated by an unknown distance d. The sources lie along a horizontal line.
Are the two sources in phase or out of phase? Explain how you can tell from the diagram. If the two sources are out of phase, give the phase difference between the two sources. Explain.
What is the source separation, d, in terms of the wavelength λ? Explain your reasoning.
A standing wave is established in a snakey as shown in the diagram at the right. The distance from point A to point B is known to be 4.69 meters. When not being vibrated as a standing wave, a single pulse introduced into the medium at point A will travel to the opposite end and back in 2.70 seconds. Determine the vibrational frequency of the wave pattern.
Each of the diagrams below represents a snapshot of two springs at an instant after a pulse has
reached the boundary between them. The linear mass density, µ, is greater for the tightly coiled
spring than for the other spring.
Each diagram may contain flaws that would not be observed with real springs. For each diagram:
a. Determine whether there is a flaw. If there is a flaw, describe it (a single flaw is sufficient)
and continue to the next diagram. If there are no flaws, answer parts b and c.
b. Make a sketch that shows the shape, width, and direction of motion of the incident pulse.
c. Determine which pulse is the reflected pulse and which is the transmitted pulse.

- The diagram (picture attached) represents two pulses traveling on a spring. Pulse A moves to the right. Pulse B moves to the left. Each pulse moves with a speed of one square per second. 1. Sketch the shape of the spring seven seconds after the instant shown. Then, eight seconds after the instant shown.arrow_forwardYou hear a seal produce an alarm call on the beach. Some of this alarm sound will also penetrate into the water to alert seals swimming underwater. Based upon your measurements of acoustic impedance, you calculate that the Reflection Coefficient R=0.5. Please answer both parts of this question and show your work. 1. How much of the sound energy will reflect back from the water into the air? Give either the proportion or the percentage. If you give the percentage, you must include the percentage sign (%) 2. How much of the sound energy will penetrate into the water? Give either the proportion or the percentage. If you give the percentage, you must include the percentage sign (%)arrow_forwardTwo loudspeakers are placed side by side a distance d = 4.00 m apart. A listener observes maximum constructive interference while standing in front of the loudspeakers, equidistant from both of them. The distance from the listener to the point halfway between the speakers is 1 = 5.00 m. One of the loudspeakers is then moved directly away from the other. Once the speaker is moved a distance r = 60.0 cm from its original position, the listener, who is not moving, observes destructive interference for the first time. Find the speed of sound in the air if both speakers emit a tone of frequency 700 Hz. Figure d/2 d/2 TR 1 82 1 of 1arrow_forward

The diagram shows a snapshot in time of the waves from the two sources, where the lines denote successive crests of the waves (solid lines from one and dashed lines from the other). 11 What is the wavelength λ of the waves? Provide a numerical answer. Draw the line on the diagram where the path difference of the waves from the two sources is always zero. Is the interference on this line constructive or destructive? Is this a nodal or an antinodal line? Mark points on the diagram where the path lengths from the two sources differ by X/2, X, 3A/2, and 2A. Join the points to draw all the possible nodal and antinodal lines. If you walk around the two sources in a large circle with 5 m radius from the midpoint of the two sources, at how many places will you experience complete sound cancellation?arrow_forwardIntroduction to Two-Source Interference Learning Goal: To gain an understanding of constructive and destructive interference. Consider two sinusoidal waves (1 and 2) of identical wavelength A, period T, and maximum amplitude A. A snapshot of one of these waves taken at a certain time is displayed in the figure below. (Figure 1) Let y₁ (z, t) and y2 (x, t) represent the displacement of each wave at position at time t. If these waves were to be in the same location (2) at the same time, they would interfere with one another. This would result in a single wave with a displacement y (z, t) given by y(z, t)= y(x, t) + y2(x, t). This equation states that at time t the displacement y (x, t) of the resulting wave at position z is the algebraic sum of the displacements of the waves 1 and 2 at position z at time t. When the maximum displacement of the resulting wave is less than the amplitude of the original waves, that is, when ymax A. the waves are said to interfere constructively because the…arrow_forward
